NEW YORK (AP) Brandon Drury has batted in big league games with blurred vision caused by migraines.

"It's something I've battled, pretty much all the time, especially with physical activity, whether it's a workout or playing ball or whatever it is," the New York Yankees infielder said Monday. "It gets worse with activity."

Drury has not played since April 6 and has been undergoing tests on his head, brain and body for the cause of the migraines. He resumed baseball activities before Monday's homestand opener against Miami. He has been put on an anti-inflammatory medication.

"I'm actually excited to figure out what's going on," he said. "I've been dealing with this for a while, and I want nothing more than to go out there and play baseball with a clear vision and a clear head."

Drury said not all the test results have come back and the issues have not yet subsided.

"We should know here in the next week if it's helping or not," he said. "It's not going to happen overnight."

Drury made his big league debut with Arizona in September 2015 and was obtained from the Diamondbacks in a February trade. He started seven of New York's first eight games at third base and was hitting .217 (5 for 23) with a home run and four RBIs when New York put him on the disabled list on April 7.

He hit .267 with 13 homers and 63 RBIs last year in his second full season with the Diamondbacks, a year after batting .282 with 16 homers and 53 RBIs.

"I think it's remarkable that he's been the player he's been, dealing with that off and on," Yankees manager Aaron Boone said.

"Maybe this explains why he hasn't been an even better player to this point in his career. Hopefully, we're getting those answers that we can get rid of this as an issue and maybe it allows him to really take off as a player."

Notes: Boone said LHP CC Sabathia is scheduled to start Thursday against Toronto. The 37-year-old was put on the DL on April 7 because of a strained right hip. He has a 4.00 ERA and no decisions in two starts. ... 1B Greg Bird played catch before the game. He is recovering from surgery on March 27 to repair a broken spur on the outside aspect of his right ankle. The Yankees projected him to return in six-to-eight weeks, but Boone said Bird appears to be ahead of schedule.
